Title: Preparation of 2, 3, 5, 6-tetrachlorobenzoyl halides and their derivatives, particularly for the production of herbicidal compositions
IPC: C07C51/62
Filed: 1956-02-08
Abstract: 2 : 3 : 5 : 6 - Tetrachlorobenzoyl halides such as the chloride and fluoride are prepared by chlorinating a benzoyl halide with chlorine in the presence of a chlorination catalyst at a temperature of 100 DEG  to 230 DEG  C. for a time sufficient to convert the reaction mixture at least partially into the desired product, and if desired, are converted into 2 : 3 : 5 : 6-tetrachlorobenzoic acid or a salt or ester thereof suitable by hydrolysis or reaction with an alcohol such as methanol or butanol.  Suitable salts are obtained by reaction with inorganic or organic bases such as alkali or alkaline-earth metal oxides, hydroxides or carbonates, ammonia or amines such as mono-, di-or tri - alkylamines and alkanolamines.  The products are used as herbicides (see Group VI).ALSO:Compositions for weed control, preventing germination, inhibiting normal growth and killing undesirable vegetation comprise as an active ingredient a 2 : 3 : 5 : 6-tetrachlorobenzyol halide such as the chloride or fluoride or a crude polychlorobenzoyl halide reaction product containing this compound, or a derivative of the halide which in the presence of water yeilds anions of 2 : 3 : 5 : 6-tetrachlorobenzoic acid, for example a salt or ester thereof (see Group IV(b)).  Suitably the polychlorobenzoic acid or salt thereof such as an alkali-metal, alkaline earth metal, ammonium or amine e.g. alkylamine or alkanolamine salt, or the amide or ester is prepared in a liquid formulation in an organic solvent, optionally in the presence of a wetting or emulsifying agent, to give an emulsifiable system or in a solid or dust formulation with solid diluents, which may also contain wetting agents.  Other herbicides may also be present.ALSO:Compositions for weed control, preventing germination, inhibiting growth and killing undesirable vegetation comprise as an active ingredient a 2 : 3 : 5 : 6-tetrachlorobenzoyl halide such as the chloride or fluoride or a crude polychlorobenzoyl halide reaction product containing this compound, or a derivative of the halide which in the presence of water yields anions of 2 : 3 : 5 : 6-tetrachlorobenzoic acid, for example a salt or ester thereof (see Group IV (b)).

Title: Severing and stacking mechanisms for plastic material
IPC: A23G7/00
Filed: 1956-02-09
Abstract: 796,373. Severing and stacking chewing gum &c. WRIGLEY, JR. CO., W. Feb. 9, 1956 [July 19, 1955], No. 4058/56. Class 87(2). Slabs of compressible material, e.g., chewing gum, are sub-divided and stacked by severing mechanism comprising rollers rotating at different speeds and a shoot disposed to receive the severed pieces. The slabs of chewing gum, already scored, are severed by the difference in the speeds of rotation of two pairs of rollers 35, 36 and 39, 40, the latter revolving faster and receiving the slabs fed to it from the former. The severed pieces 44 fall into a shoot 45 and become stacked in it. Each roller has a series of rows of serrations, 59-65 on roller 39, Fig. 3, and 78-84 on roller 40, pairs of such rows, e.g., 59 and 78, being opposite, and the serrations are skewed so that the depressions made thereby on opposite sides of the material are criss-cross, to minimize premature breakage of the material. The serrations are oppositely skewed as between the half-lengths of each roller, to balance the angular forces. The rollers 35, 36 are similarly provided with opposite rows of serrations but, except for the outside ones, the pairs of rows are not in line with those of the rollers 39, 40, Fig. 5. In the middle and near the ends the diameter of the rollers is reduced to less than the root diameter of the rows of serrations, e.g., in the roller 35 by grooves 104, 105, 106. The form of the serrations is shown in Fig. 6. The tops 114 are flattened to minimize wear and the spaces 67 between them are curved, providing a self-cleaning action for, e.g., sugar coated chewing gum. Sugar which tends to accumulate near the outer ends of the serrations is pushed along the bottoms of the spaces and escapes by way of the grooves, e.g., 104-106. The severed pieces are discharged from between the rollers 39, 40, Fig. 9, assisted by fingers 115 which enter their end grooves. Each finger comprises two parts 117 and 118, the main part 117 being pivoted about a cross shaft 133 and biased towards the roller 39 by a spring 140 (limited by a stop screw 138) and the auxiliary part 118 being pivoted on the main part and biased by a spring 124 to cause its end to pass that of the main part, which is suitably forked. When the front of a severed piece 44 passes under the inclined surface 146 of the end of the main part the end of the auxiliary part rises but the spring 124 causes it to return and to press the rear of the piece 44 against the roller 40, so directing it to the stack in the shoot out of the path of succeeding pieces. The end 123 of the auxiliary part has serrations to wear away any sugar which might clog the parts. The main part has a projection 148 which is normally above the stack and if a piece becomes jammed or bent, Fig. 10, the main part is forced upwards, causing an arm 149 to rise and actuate the spring arm 156 of a switch 153 and stop the machine.

Title: Laminated products and method of making same
IPC: D21J1/00
Filed: 1928-02-10
Abstract: 300,836. Marks, E. C. R., (Bakelite Corporation). Feb. 10, 1928. Boards and compound paper; paper, treating with special materials.-Laminated sheet material is made from sheets of fibrous material, which may be paper or cardboard, impregnated with an artificial resin of the glycerol-phthalic anhydride type and bonded together by a phenolic resin. The resin is of the type which results from the interaction of polybasic alcohols with phthalic anhydride, either alone or mixed with acids such as succinic. oleic or stearic acid, and the sheets may be impregnated by treatment with a solution of the resin, or by combining the resin in a fine state of division with loose fibrous material which is afterwards made into paper or board. The sheets are then heated to 100‹-150‹ C. to convert the resin into infusible form. The impregnated sheets are then coated with a reactive varnish of the phenol-methylene type, dried to expel the solvent, and assembled and consolidated by heat and pressure. Alternatively sheets of absorbent paper impregnated with reactive phenolic resin may be interposed between the fibrous sheets impregnated with the glycerolphthalic anhydride resin, and the whole dried and consolidated by heat and pressure. Exterior or facing sheets of paper or fabric impregnated with phenol-methylene resin may be provided.

Title: Improvements in and relating to motor starters and circuit controllers
IPC: H02P1/02
Filed: 1922-02-15
Abstract: 175,632. Burke, A. W. Feb. 15, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Automatic circuit-breakers for use in starting small motors are constructed with an overload magnet which is moved further away from its armature during the action of closing the switch, in order to raise the tripping point, and is returned to its normal setting by continuing the movement of the closing handle, or by automatic means. Figs. 1 and 2 show the mechanism of the switch in the open position, and Fig. 4 in the closed position. The movable contact 7, pivoted on a spindle 2, is closed by turning a handle on a spindle 26. When the handle has been turned as far as it will go, spring-controlled members 9, 14 assume the position shown in Fig. 4, and the overload magnet 21 is swung about a pivot 23 away from the armature 19, the change of overload setting being indicated by a pointer 31. The switch tends to close under the action of a spring 5, but does not actually close until the handle has been moved slightly back so as to remove an obstructing cam 34 out of the path of a member 36. As long as the handle is not turned further back the switch remains closed at the less sensitive overload setting. When the handle is turned right back, a cam 29 allows the magnet to be swung to its normal position by a spring 24. The tripping action in case of overload takes effect through the armature 19 rocking a lever 18 which raises a trigger arm 14 out of engagement with an arm 9 tending constantly to open the switch under the action of a spring 11. The switch can also be tripped manually by turning the handle. In a modified construction, the return of the magnet to normal setting, after the switch has been closed, proceeds automatically under the control of a dash-pot. The switch mechanism is mounted on the inside of a cover 38, Fig. 3, and is provided with line-connectors 40 which join up with terminals 41 on a box 37. A removable inside cover 3 is attached to the stationary switch contact 8.
